3.6.2.
System with Two or More
Transmitters in One Room
When radiators in one multipurpose room are
connected to two transmitters, an extra signal delay
is added by:
Transmission from master transmitter to
bypass transmitter (cable signal delay)
Transmission through the bypass transmitter.
Use the following procedure to determine the delay
switch positions in bypass mode:
1
.
According to the procedures for a system with
one transmitter, calculate the cable signal delay
for each
radiator in Hall-1 and Hall-2;
2
.
Calculate the signal delay between the master
and the bypass transmitter (Table 3.2);
3
.
Add the master-to-bypass signal delay to each
radiator connected to the bypass transmitter in
Hall-2;
4
.
Determine the maximum signal delay;
5
.
For each radiator calculate the signal delay
difference by subtracting the cable signal delay
from the maximum signal delay
6
.
Divide the signal delay difference by 25. The
rounded off number is the signal delay switch
position for the radiator;
7
.
If needed, add delay switch positions to
radiators under a balcony;
8
.
Set the delay switches to the calculated delay
switch positions.
Figure 3.16, Table 3.2 and Table 3.3 illustrate the calculation of the extra master- bypass signal delay
.

Note:
If a master-bypass mode is used for two
rooms that are always separated, the
delay switch positions can be calculated
separately for each system and the delay
caused by transmission from master to
bypass transmitter can be ignored.
